The Mexican Government has made a formal complaint to the President of the United States, in relation to the Indian outrages along the frontier, which the United States were bound to suppress, according to the Treaty of Guadaloupe Hidalgo. It is believed that a demand of a million of dollars will be made for damages which the Indians have already caused; besides which, Mexico refuses to ratify the Tchuantepec Treaty, unless these provisions are fulfilled. At the last session of Congress, the appropriation asked by the War Department for this purpose, was not made; besides which, the troops most serviceable for such a warfare have been disbanded. An order has been issued by the President, that the tracts of land in Iowa, occupied by General Ujhazy and the other Hungarian exiles, shall be withheld from sale until the end of the next session of Congress, with a view to making application to that body for a grant of the lands. The Massachusetts Legislature, after a struggle of four months, succeeded in electing a U. S. Senator on the 24th of April. Charles Sumner, Esq., the Free Soil Candidate, was chosen on that day, by 193 votes, precisely the number necessary for election. The Boston Board of Aldermen, who had passed a resolution refusing the use of Faneuil Hall for a public address by Daniel Webster, have since then retracted the step and concurred with the Common Council in inviting Mr. Webster to address the citizens of Boston. Faneuil Hall, hereafter, is to be granted on all occasions, at the application of one hundred voters. Before leaving Boston, Mr. Webster delivered a speech to the citizens of Boston, from the steps of the Revere House. The Legislature of New-York adjourned on the 17th of April. The question of the enlargement of the Erie Canal was before the Senate, when twelve of the Democratic members of that body resigned their seats in order to prevent the passage of the bill, by leaving the senate without a quorum. The usual annual appropriations had not been voted, and the Government was thus placed without the means of sustaining its operations. An extra session of the Legislature has been called by Governor Hunt, for the 10th of June. Elections have been ordered, in the mean time, to fill the vacancies caused by the resignation of the Senators. The Members of the Assembly, of both parties, published manifestoes in relation to the question.
